DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0025] In the description of this application, it should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, technologies, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0026] Example 1:

[0027] like Figure 1-Figure 3 As shown, this embodiment provides an exhaust device for a powder spraying room, comprising an exhaust fan 1, an exhaust duct 2, and a purification cylinder 3. The exhaust fan 1 is used to extract air from the powder spraying room. The exhaust duct 2 is located on one side of the exhaust fan 1, one end of which is connected to the exhaust fan 1 and the other end extends into the purification cylinder 3. The purification cylinder 3 is located on one side of the exhaust fan 1 and is connected to the exhaust fan 1 to purify the extracted exhaust gas.

[0028] A filtration system is provided in the purification cylinder 3, and the filtration system includes a detachable filter 4, which can remove dust and harmful substances in the extracted exhaust gas;

[0029] The sound reduction cover 5 is arranged outside the purification cylinder 3 and covers the exhaust fan 1 and the exhaust duct 2 to reduce the noise generated by the exhaust fan 1 when it is working.

[0030] In this technical solution, the exhaust device of the powder spraying room effectively extracts the waste gas generated during the powder spraying process and reduces the noise generated when the equipment is running.

[0031] 1. Exhaust gas extraction: The exhaust gas in the powder spraying room is quickly extracted by the exhaust fan 1 to reduce the concentration of harmful substances in the room and ensure the safety of workers and environmental hygiene.

[0032] 2. Exhaust gas purification: The filtration system in the purification cylinder 3 removes dust and harmful substances from the exhaust gas to meet environmental emission standards.

[0033] 3. Noise control: By arranging a sound reduction cover 5 outside the purification cylinder 3, the noise generated by the exhaust fan 1 during operation is reduced, thereby improving the working environment.

[0034] Workflow:

[0035] When the powder spraying operation begins, the exhaust fan 1 is started to suck in the air in the powder spraying room, and the waste gas containing dust and harmful substances is sent to the purification cylinder 3 through the exhaust duct 2. The extracted waste gas enters the purification cylinder 3 and passes through the filtration system. The filter 4 plays a role in this stage, removing dust and harmful substances in the air; the filter 4 is detachable, which is convenient for regular cleaning or replacement to ensure a long-lasting filtering effect. The noise generated by the exhaust fan 1 during operation is effectively controlled by the sound reduction hood 5. The design of the sound reduction hood 5 allows the noise to be absorbed and attenuated before being discharged to the external environment. The purified air can be released to the external environment through appropriate discharge methods to ensure that the emissions meet relevant environmental protection standards. Through this powder spraying room exhaust device, the exhaust gas emissions in the powder spraying operation can be efficiently controlled, while reducing operating noise, creating a safer and healthier working environment. This design not only meets the requirements of safety and environmental protection, but also improves work efficiency and employee comfort.

[0036] like Figure 1 and Figure 3 As shown, in this embodiment, the sound reduction cover 5 is optimized and made of sound insulation material.

[0037] In this technical solution, the sound reduction cover 5 is made of sound insulation material, and its main purpose is to further reduce the noise generated when the equipment is running, protect the hearing of employees and improve the comfort of the working environment.

[0038] 1. Noise reduction: The sound attenuation cover 5 effectively absorbs and attenuates the noise generated by the exhaust fan 1 during operation, thereby reducing the noise level.

[0039] 2. Environmental protection: By reducing noise, the impact on the surrounding environment is reduced and the relevant noise control regulations are complied with.

[0040] 3. Improve work comfort: Create a quieter working environment for employees, improve work efficiency and satisfaction.

[0041] Workflow:

[0042] When the exhaust fan 1 is started and running, it will generate a certain amount of noise. This noise mainly comes from the rotation of the fan, the air flow through the pipe, and other mechanical vibrations. The noise is transmitted to the sound-attenuating hood 5 through the exhaust duct 2. Inside the sound-attenuating hood 5, the sound insulation material (such as mineral wool, polyurethane foam or heavy polymer) used can effectively absorb sound waves and reduce the reflection and propagation of sound waves. The sound absorption performance of the sound insulation material will attenuate the noise inside the hood, thereby reducing the noise level transmitted to the external environment. After the noise is attenuated, the exhaust fan 1 continues to discharge the purified air to the outside. At this time, the discharged air not only meets environmental protection standards, but also the noise is within an acceptable range. The effectiveness of the sound insulation material depends on its maintenance. Regular inspection and cleaning of the sound-attenuating hood 5 can ensure that its sound absorption effect is maintained for a long time, further improving the comfort of the working environment. The sound-attenuating hood 5 made of sound insulation material can not only reduce the noise of the powder spray booth exhaust device, but also improve the quality of the overall working environment. By optimizing noise control measures, it ensures the health and safety of employees and improves production efficiency.

[0043] like Figure 1-Figure 3 As shown, in this embodiment, the filter 4 is optimized and includes a filter element 41, a spray plate 42 and a spray head 43. The filter element 41 is arranged in the purification cylinder 3, the spray plate 42 is arranged on the filter element 41, and the spray head 43 is arranged on the spray plate 42 and faces the filter element 41; the spray plate 42 is a hollow structure, and the hollow structure of the spray plate 42 extends outside the purification cylinder 3 to guide dust into.

[0044] In this technical solution, the filter 4 improves the exhaust gas purification effect and operation efficiency by combining the filter element 41, the spray plate 42 and the spray head 43.

[0045] 1. High-efficiency filtration: The filter element 41 removes dust and harmful substances from the exhaust gas, ensuring that the exhaust air meets environmental protection standards.

[0046] 2. Water washing function: The spray plate 42 and the spray head 43 can clean the filter element 41 by spraying water, thereby reducing dust accumulation and increasing the service life of the filter element.

[0047] 3. Dust guidance: The hollow structure of the spray plate 42 can effectively guide the incoming dust, enhance the filtration efficiency, and ensure cleaner air discharge.

[0048] Workflow:

[0049] When exhaust fan 1 is activated, exhaust gas from the powder spray booth is extracted and transported through exhaust duct 2 to purification cartridge 3. Upon entering purification cartridge 3, the exhaust gas first passes through filter element 41. The filter element's structural design captures most of the dust and harmful substances in the exhaust gas, reducing emissions. As the exhaust gas passes through filter element 41, a spray head 43 sprays water mist, which is dispersed onto the surface of filter element 41 via spray plate 42. This process helps wet the filter element and further captures fine particles. The hollow structure of spray plate 42 guides and concentrates dust in the exhaust gas downward, preventing it from accumulating on the filter element, ensuring more efficient air circulation and filtration. After spraying and filtering, the air is discharged to the outside through purification cartridge 3, meeting environmental standards and protecting the environment and worker health. The design of this filtration system, through the introduction of spray plate 42 and spray head 43, not only improves the efficiency of the powder spray booth's exhaust gas treatment, but also enhances the cleaning and maintenance capabilities of the filter element, ensuring long-term, stable operation. This comprehensive purification solution provides strong support for the environmental protection and safety of the powder spray booth.

[0050] like Figure 1-Figure 3 As shown, in this embodiment, the optimized, detachable filter 4 is connected to the purification cartridge 3 by means of bolts.

[0051] In this technical solution, the detachable filter 4 is connected to the purification cartridge 3 by bolts, providing convenient maintenance and higher filtration efficiency. Its main functions include:

[0052] 1. Easy maintenance: The bolt connection design allows the filter 4 to be quickly disassembled, making it easy to clean and replace, reducing maintenance time.

[0053] 2. Stability: The bolt connection ensures a secure connection between the filter 4 and the purification cartridge 3 to prevent leakage or loosening during operation.

[0054] 3. Improve filtering effect: The detachable design allows the filter 4 to use more efficient materials, thereby improving the exhaust gas purification capability.

[0055] Workflow:

[0056] When the exhaust fan 1 is working, the exhaust gas in the powder spraying room is sucked into the purification cylinder 3 through the exhaust fan 1, and the exhaust gas flows through the filter 4. The filter 4 captures dust and harmful substances to ensure that most pollutants are removed. When the filter 4 needs to be cleaned or replaced, the operator can use a tool to loosen the bolts and easily remove the filter 4 from the purification cylinder 3. After cleaning or replacement, the filter 4 is reinstalled and the bolts are fixed to ensure its sealing with the purification cylinder 3. After the filter 4 is reinstalled, the system can continue to operate and maintain the efficiency and stability of the exhaust gas treatment. The design of the detachable filter 4 connected by bolts not only improves the stability and sealing of the filter 4, but also greatly facilitates maintenance work, ensuring that the exhaust device of the powder spraying room can operate efficiently and for a long time.

[0057] Example 2:

[0058] This embodiment provides an exhaust device for a powder spraying room, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] like Figure 4 As shown, in this embodiment, it is optimized and further includes a wind speed regulator 6, which is used to adjust the wind speed of the exhaust fan 1 according to the working state of the powder spraying room.

[0060] like Figure 4 As shown, in this embodiment, the wind speed regulator 6 is optimized to include a manual adjustment unit 61 and an automatic monitoring system 62. The manual adjustment unit 61 is used for manual adjustment by the user, and the automatic monitoring system 62 adjusts the wind speed in real time according to the air quality in the powder spraying room.

[0061] In this technical solution, the wind speed regulator 6 of the powder spray booth exhaust device is designed to flexibly adjust the wind speed of the exhaust fan 1 according to the working state of the powder spray booth to improve work efficiency and environmental control. Its main functions include:

[0062] 1. Flexible adjustment: Users can manually adjust the wind speed according to actual needs to adapt to the requirements of different powder spraying operations.

[0063] 2. Automatic monitoring: The automatic monitoring system 62 monitors the air quality in the powder spraying room in real time and automatically adjusts the wind speed to ensure a safe and comfortable environment.

[0064] 3. Energy-saving effect: Adjust wind speed according to actual needs to avoid unnecessary energy consumption and improve energy utilization efficiency.

[0065] Workflow:

[0066] Automatic monitoring system 62 continuously monitors the air quality in the powder spray booth, analyzing dust concentration and harmful substance levels. If it detects a decrease in air quality, it automatically increases the wind speed of exhaust fan 1 to improve exhaust gas extraction efficiency. Conversely, if the air quality is good, the system appropriately reduces the wind speed to save energy. Operators can manually adjust the wind speed at any time based on work needs through manual adjustment unit 61. For example, a higher wind speed may be required at the beginning of the powder spray operation, while the wind speed can be reduced after completion. Wind speed regulator 6 provides real-time feedback on current wind speed and air quality, ensuring that operators can make timely decisions and maintain an optimal working environment. By introducing wind speed regulator 6, the powder spray booth exhaust system can flexibly adjust the wind speed based on actual working conditions, realizing a combined manual and automatic adjustment mechanism.
